[5-10] Speed/acceleration override (schematic diagram)
"Override" is the change of profile parameters and their acceptance during the positioning
process.
In this case, the travel profile is adapted accordingly to ensure that the defined target
position is still exactly approached if, for example, the speed is changed during the
positioning process ("speed override"):

n The speed is reduced during the positioning
process.
o To reach the defined position, the missing
surface must be "attached" to the profile.
p When the speed is reduced the positioning
process takes a longer time (Δt).
